Optical Coherence Tomography-Based Quantification of Photoreceptor Injury and Recovery in Vogt–Koyanagi–Harada Uveitis
Bibliographic record
Abstract
PURPOSE: To determine if the inflammatory composition of subretinal fluid in Vogt-Koyanagi-Harada (VKH) serous retinal detachments is predictive of photoreceptor injury, and to quantify photoreceptor recovery, following resolution of these detachments. METHODS: Optical density (OD) measurements of spectral-domain optical coherence tomography (SD-OCT) scans were used to derive the fibrinous index, a measure of the inflammatory composition of subretinal fluid. In order to assess photoreceptor status, photoreceptor outer segment (PROS) volume was measured from SD-OCT scans. RESULTS: The fibrinous index of subretinal fluid in VKH uveitis was strongly correlated with the PROS volume following resolution of subretinal fluid (r = -0.70, p = 0.006). Following fluid resolution, both PROS volume (p < 0.0001) and visual acuity (p = 0.0015) improved. CONCLUSIONS: The fibrinous index of subretinal fluid during the acute stage of VKH can predict photoreceptor status following resolution of subretinal fluid. PROS volume is a useful measure of photoreceptor recovery in VKH.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
